Be it known that I, DANIEL MAsoR, a citi- Zen of the United States, residing at 236()- Lor'illard Place, Bronx, in the city and beam l2 when the clamp is secured in pltre.' A bolt 1 preferably of the shape shown in Fig. l, is' held within the block 4 and projects at one end through the slotted opening have invented new and in Adjustable Clamps, ing is a specification.

This invention relates to certain .new and useful improvements in adjustable clamps and has for its ob` ject to provide a device of this character that is simple in construction, cheap to man ufacture and one that'can be readily applied and quickly adjusted when necessary.

With these and other objects in view, the

useful Improvements or which the followengage the end of the channel beam' 12 o posite the depending flange ll. or threaded end of the bolt 13 passes at lright angles through a slot 1G in the sloping top wall 9, and is provided with a nut 17 by which it is securely fastened in place. By reason of the bolt being made of the form shown and cooperating at right angles with the sloping top wall'9, it will be seen that when the nut 17 is tightened, the hook not only has an upward or direct pull but a laterallI pull toward the depending fiange 11 as we In the modified form shown in Figs. l and 5, the construction is somewhat similar to that shown in Figs. l to 3. In this form have shownniyimproved clamp for conn necting I beams and channel uprights. v The clamp is held to the channel upright in the same manner as the preferred 18 is straight, being provided with the hook 19 for engaging4 one flange of the I beam, and held in an inclined manner by the inclined side wall 20 through which it passes. An inward ly'depending hook 2lv proj ects from the clamp and engages the other liange of the beam as shown, and it may be seen that when the bolt 18 is tightened, the hook 19 is drawn against` one flange of the I beam and the hook 21 engages the other flange of the I beam securely connecting the beam and construction and combination of parts .more fullyhereinafter described and particularly pointed out in the claims. i

, Referring to the drawings forming; a part' of this specification in which like reference characters'refer to like parts throughout the several views,-Figure l is a front view of my improved device shown connecting a broken away for the sake of clearness. Fig. 2 is a plan view of the parts shown in Fig. l. Fig. 3 is a side elevational view of the parts shown in Figs. 1 and 2, but looking toward the right. Fig. 4 is a front elevational view of a modified form of clamp also shown connecting a beam and upright, and Fig. 5 is a Heretofor? in the joining of bealus andl uprights in structural, iron Work, difficulty has been experienced in drilling themnecessary holes and providing the proper' uniting means, and a great deal of valuable time is lost in the operation, therefore l' propose by the use of my invention to eliminate all of these objectional features and accomplish the desired result in a quick and cheap manner. f

In theorm of device shown in Figs. l to 3, my adjustable clamp comprises the horizontal base l provided with the vertical rear wall 2, sides 3 and front block or housing 4C; 5 indicates a slot provided in the rearv wall 2 for receiving a bolt for securing the clamp to the upright channel 7. The front with the in! clined front wall 8 and sloping top wall 9, which is extended at its remto form a depending ange 11 which an'ge is adapted to engage and` grip the side of the channel channel together.

From the foregoing, it may'be seen that my improved radjustable clamp may be quickly put into operation in structural construction or readily taken 'apart when desired. .j It is obvious that many other variations may be madein the details of construction and combination of partswithout departing from the spirit and scope of my invention, therefore, I. do not Wish to be limited to the exact construction as shown..

l. In a clamp for uniting beams and uprights in structural iron work, the combina'- tion of a base plate, a iange formed on said base plate and adapted to engage one side of the said beam, a clamp bolt disposed oppositely to said depending fiange'and adapted 14, in the inclined front wall 8., and 1s bentl form but boltv side of the said beam and to engage the other side ef the said beam, an `upright Wall provided With a horizontally disposed slot and mounted on said base plate, and a bolt mounted within said slot for connecting' said clamp to said upright, substantially as described.

2. In an adjustable clamp for uniting beams and uprights in structural iron Work, the combination of a base plate, a depending flange arranged on the said base plate and adaptedto engage on'el side of the said beam, a block or housing provided with angularly disposed slots and mounted on the said base plate, a clamping bolt mounted Within the said slots and adapted to engage the other means for connecting the said clamp to the said uprightsubstantially as described.

3. a clamp for uniting beams and uprights instructural iron work, the combination of a base plate, a depending llange mounted on the said base plate and adapted to engage one side of the said beam, a block or housing mounted on the said base plate and provided with a sloping top wall and au inclined front wall, both of said walls being provided with slot-s, a clamping bolt mounted Within the said slots and adapted to engage the other side of the said beam,

an upright Wall mounted on the said base ik
